If you didn’t like Michael Bay’s Teenage Mutant Ninja Turtles movie, just know that it could’ve been a lot worse. An early draft of the script turned the Turtles into aliens from another dimension and Shredder was turned into Colonel Schroeder, a secret alien who can grow blades. That’s just one of the facts packed into the latest episode of You Think You Know Movies, which gets totally tubular with the Teenage Mutant Ninja Turtles!

Megan Fox had previously worked with Ninja Turtles producer Michael Bay on the first two Transformers movies. She was fired from the third movie by Steven Spielberg after she said of Bay, “He wants to create this insane, infamous mad-man reputation. He wants to be like Hitler on his sets, and he is. So he's a nightmare to work for.” Fox and Bay must’ve somehow mended fences because she was cast in the Turtles movie and later would describe working with him again as “lovely”.
